White won't play the next few moves accurately. I think he lacked a bit of energy and subtlety to avoid Black's counterplay.
9... e6c4  10. f1c4  10... f8g7 This move is criticized by the computer, but the alternative the machine offers is depressing, leading to a painful ending for Black, everything Arjun didn't want when choosing this opening line. 11. e1g1  11... e8g8 The computer already gives White a more or less a 1.5 advantage here, which is surprising to me, as I didn't think it was that bad for Black.
